WATCH.

Patented May 11, 1920.

Application filed September 18, 1919. Serial No. 324,354.

To all whom it may concern:

Be it known that we, PHILIP BENJAMIN, a citizen of the United States, and a resident of the borough and county of Bronx, city and State of New York, and SAMUEL BURGER, a citizen of the United States, and a resident of the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Watches, of which the following is a specification.

While applicable to watches generally, our improvements are designed more particularly for use in conjunction with the relatively small wrist watches at present in vogue,the main object being to facilitate the withdrawal of the works for purposes of exhibition, inspection, or regulation, and their replacement in the watch casing in the simplest manner possible. To this end our invention consists in the specific construction and arrangement of parts described and claimed, distinctive features being the formation of the casing in such manner that the works-frame may be withdrawn or inserted laterally, through the edge of the casing,-in contradistinction to'the method of countersinking the works and workframe in the outer casing as heretofore, and in the interlocking means for detachably securing the parts together, all as hereinafter fully set forth.

In the accompanying drawings, in which the parts, for convenience of illustration, are shown upon a relatively large scale,

Fig. 20, is a face view of the watch as shown in Fig. 19;

Fig. 21, is a top view thereof;

Fig. 22, is a face view of the works-frame. shown in Figs. 19 and 20, removed from its casing;

Fig. 23, is an end view of the watch shown in Figs. 19 and 20;

Fig. 24:, is a cross section of the casing. taken upon plane of line o o, Fig. 10.

The watch case C, may be of any desired configuration externally, provided it is formed with the pocket or recess 0, adapted to accommodate the works-frame W. and with an edge opening 0, through which said works-frame W, may be inserted or removed. That is to say. except for the said aperture 0', and the dial-sight opening 0 in its face 0 the casing C, is closed on all sides,the front 0 back 0. bottom edge 0 and side edge walls 0 being continuous and integral. When designed for a wrist watch. as shown in the accompanying drawings, the side edge walls c", o, are provided with loops 0 o, for attachment to a suitable strap, ribbon, or other wrist band in a manner well known in the art.

The aperture 0', in the top edge of the casing C, is of a shape and area just sufiicient to accommodate the works-frame W,

inserted edgewise. Preferably the pocket or recess 0, is of like length and width, although this is not an essential feature, as it might be larger in some designs. A watch movement is mounted entirely within and upon the works-frame W, the front side of which bears the dial "d, and the rear side of which is open (when not in the casing C) to give access to the movement regulator 1", etc., in the usual manner, as indicated particularly in Fig. '6.

The works-frame W, is detachably secured to and within the casing C, by means of any'suitable mechanical expedient, as we do not limit our invention in this respect, the essential feature in this connection being the edge aperture 0, in the casing C, for the insertion or removal of the worksframe W, in alinement with the mean plane of the said casing, substantially as herein set forth. By preference we use a snap fastening or fastenings, as shown in the drawings, for thus detachably connecting the works-frame to the casing C. Thus in the first eighteen figures of the drawings, an elastic, resilient snap hook 0 attached to the back plate 0, 'of the casing is provided for engagement with a shoulder 10, on the works-frame IV, as shown more particularly in Fig. 18, while in the remaining figures two elastic resilient spring detents w, w, on the works-frame WV, perform the same function by engaging with notches 0", 0 formed for the purpose in the inner sides of the end walls 0", 0 as shown more particularly in Fig. 19. In either case the pushing back of the spring detent means effects the release of the works-frame W, from the casing C, while the act of inserting the works-frame W, fully into the recess a, of the casing C, automatically effects the interlocking of the parts.

Where the snap hook 0 is used it is preferably positioned centrally and countersunk in a depression formed for it in the back plate '0 of the casing as indicated in Figs. 10 and 15, a cap plate 0 being soldered to the inner side of the back plate 0*, to retain the shank of the snap hook 0 in position by means of an indentation 0 formed therein as indicated in Figs. 14: and 15. Where the two spring detents w, w, are employed, their shanks may be secured to the worksframe W, by studs w, w, or by any other desired mechanical expedient.

It is to be understood that the expedients for e'fle'cting'the interlocking of the casing C, and works-plate W, herein shown and described are by way of illustration only,

and that other interlocking means may be substituted therefor with like result and without departing from the spirit and intentof our invention in this respect. Also,

"that'the design or configuration of 'the casing etc., is of secondary importance provided provision is made for effecting the insertion and removal of the works-frame through a suitable aperture in one edge of the casing, and in alinement therewith, in contradistinction to the old method of mounting the works-frame in a relatively permanent manner in a countersink in the casing, as heretofore.

The advantages attained by our invention are numerous, and of practical importance. The facility with which the works-frame W, may thus be withdrawn from and reinstated in the casing is an advantage to the salesman; to the customer who wishes to regulate the movement, or exhibit the jewelingof the works etc.; to the watch-inspector and repairer, and soon; while the security and protection afforded the works is ample in every particular.

The illustration of our improvements as applied to a wrist watch is only incidental, as the essential features thereof are applicable to pocket and other kinds of watches.

What we claim as our invention and desire to secure by Letters Patent is,

1. In combination, a watch casing formed with an edge aperture, a works-frame adapted to be inserted into and removed from said casing through said edge aperture, in alinement w th the mean plane of said casing. and means for detachably securing said casing and works-frame together, said casing forming the case for the works-frame. for the purpose described.

2. In combination, a watch casing formed with an edge aperture, a works-frame adapted to be inserted into and removed from said casing through said edge aperture in alinement with the mean plane of said casing, said casing forming the case for the works-frame, and elastic resilient means for detachably securing the said casing and works-frame together, for the purpose described.

In combination, a watch casing formed with an edge aperture, a works-frame adapted to be inserted into and removed from said casing through said edge aperture in alinement with the mean plane of said casing, said casing forming the case for the work's -frame, and interlocking means for detachably securing the said casing and works-frame together, for the pun pose described.

4. In combination, a wrist watch casing formed with an edge aperture, a worksframe adapted to be inserted into and removed from said. casing through said edge aperture in alinement with the mean plane of said casing. said casing forming the case for the works-frame. and means for detachablv securing said casing and works-frame to ether. for the purpose described.

5. In combination, a relatively flat watch casing formed with an edge aperture, a correspondingly flat Works-frame adapted to be inserted into and removed from said casing through said edge aperture in alinement With the main plane of said casing, said casing forming the case for the Worksframe, and spring latch mechanism for releasably securing the said casing and worksframe, for the purpose described.
